Converting existing metal garage door to electric operation

[davidk65]

Our existing metal door is the type with a rod and spring (above the door)that goes across the door inside the garage, with metal slide rails down each side.It's is a double garage and I think the door type is referred to as Canopy or Up-and-over door.
Having spent a little time looking at the web for information, what I have found has all been about doors that have a pair of springs on each side and I have not been able to find specific instructions for our type of door. The suggestion being that our type of door does not convert easily.
Any suggestion on conversion and fitting welcome.

Known in the trade as "fitting new to old" ................ not always the best option David. I only say this because your door sounds as though it's getting on a bit. If so, your shiny new electric gear could be made useless if the door starts to play up, and has to be scrapped.
Check prices for a total replacement first. It might be cost-effective.
I've done some Googling for you too, and I haven't found anything either!

Cardale uses a different assembly and cartridge.
I think you will need complete replacement assy.

Thank you. Sound advice. I have started the the process of getting prices. At least one installer is coming to have a look next week with 2 options in mind; convert existing or fit new. I am told that on new garage doors the trend is to go away from a one piece door, which mine is, the new ones move in sections (think a bit like a roller door but not quite like that). I have tried other installers but no response I guess they might still be on holiday.
Thank you.
